3Installation
·
Blowout airlineandpressure hose,prior toconnection ittothetool.
· Makesure,thatall air lineshaveasufficientcross-section(see technical
data)andhosesmustbefree ofbends andkinks. The hoselengthshould
not exceed2meters.
· All DEPRAGScrewdrivers, maybe operatedeither withorwithout
lubricatedair(see paragraph: Maintenanceand Upkeep). Best resultsare
achieved, when machineislubricatedwith1–2dropsofoil per1m3.
Whenoperatingwithoilfree air,aperformancereductionof upto20%
occursandmaintenancerequirementsincreases!
· Connect the equipment asfollows:
a) for standardoperation connectequipmenttoamaintenanceunit,

OUR RECOMMENDATION: The preferred lubricatingmethod for the
screwdriver spindles mountedinfixtures,brackets,machines,etc.,eachin
connection withacontroller,ismethodb) withPoint-of-UseOiler.
· Checkpressureat directlyon the machine.The Regulatorneedstobe
adjusted toanairflowbetween 5.0(71PSI)and6.3bar(90PSI).Ahigher
pressureleadstoincreased wear andtear.Alower pressure maylead to
clutchnot being abletocorrectlyshut-offthe motor.

4Operation
Unlessotherwiserequested thedriver ispresettomax.torque withthe
strongest clutchspring.Adjustclutchtotherequired torquevalue. If
necessary, exchange clutchspring.
Operatingtheclutchusing aclutchspring whichexceeds its
allowable torque,leadstoareductionofthetorque accuracy.
The necessarytorque adjustmentcanbe tested, usingaDEPRAG Torque
Wrenchor Dynamometer (see DEPRAGcatalogsD3020and D3022).This
equipmentcanalsobe usedtore-adjustthe torqueoftheScrewdriver
Spindle.
Attention:
Push-to-start-screwdriver!
The flowpressure should notdropbelow5bar (71PSI)!
The installationandconnectionofthe Screwdriver Spindle requiresthe
following steps:
1.Adjustclutchtorequired torquesetting(see paragraph: Torque
Adjustment).
2.InstallScrewdriver spindleaccordingtopicture: „Installation Tips for
screwdriverspindle“.
3.Connectmainairhose.
4.Connectpneumaticfunctioncontrolhose.Thisfunctioncontrolisunder
pressureof2,5bar during actual screw-driving. Ifthefunction control
isnotneeded, theporthastobeclosed, otherwisethereisalossof
power of about15 %.
Pleasemakesurenottoexceed the max. driver stroke(see Installation Tips
for screwdriverspindle)during Screwdriving. The noiselevel can befurther
reduced,when an exhaust connection withconnectedFilter/Silenceris used.

Toavoid loosingindividual small parts, it isrecommendedto
onlydisassemblethe machine ontop of aflatworksurface.
1.Disconnectdriver fromair supply.
2.Unscrewclutchbearing completewithspringsleeve(Accessories-Op-

4.4Connection-PossibilitiesoftheFunction Control
·
Use as air pressureoutletduring screw-assembly:
- tocontroldriver start and stop,as well asshut-offcontrol ofclutch;
- ascycle counterof the completeprocess;
eachin connectionwithaPE-Switchorsimilar.
· Use as air pressureinlet:
- if 6,3bar(90PSI)air pressure isgiven tothefunctioncontrol port,
the driver starts rotatingatabout15 %ofitsspeed.Thiswill
simplifytheengagement ofbit/sockettofastener(for example
when driving hexscrews, nuts, etc.)
